I am thinking oversized Aquarium Gravel Vac. My pond is above ground so I
can start a siphon, clean the pond and water the plants. I was thinking of
say a 4 foot long piece of 3" dia pipe adapted to a piece of corrugated sump
pump discharge hose. I could cut the pipe in half and have a threaded
section to shorten the pipe when needed. I could clean from the edge of the
pond so I could suck more muck out then stir up when you have to wade in up
to your privates. Not to mention it would be easy and cheap.
